![]() Instances that share that same ArrayBuffer to become unusable.Understanding JavaScript’s Execution Modelīefore we get going, it’s important to make sure we understand JavaScript’s execution model correctly.Ĭonsider the following Ruby code: require 'net/http' require 'json' Great care must be taken when using a transfer list to transfer anĪrrayBuffer as doing so causes all TypedArray and Buffer It is possible and commonįor multiple views to be created over the same ArrayBuffer instance. Way of viewing and manipulating the data. The raw data while the TypedArray and Buffer objects provide a That is, it is the ArrayBuffer that actually stores Considerations when transferring TypedArrays and Buffers #Īll TypedArray and Buffer instances are views over an underlyingĪrrayBuffer. The message object is cloned immediately, and can be modified afterįor more information on the serialization and deserialization mechanismsīehind this API, see the serialization API of the node:v8 module. exports = function parseJSAsync( script), ) copy Worker, isMainThread, parentPort, workerData, So by transferring ArrayBuffer instances or sharing SharedArrayBuffer Unlike child_process or cluster, worker_threads can share memory. The Node.js built-inĪsynchronous I/O operations are more efficient than Workers can be. They do not help much with I/O-intensive work. ![]() Workers (threads) are useful for performing CPU-intensive JavaScript operations. To access it: const worker = require( 'node:worker_threads') copy The node:worker_threads module enables the use of threads that execute Launching worker threads from preload scripts.Considerations when cloning objects with prototypes, classes, and accessors.Considerations when transferring TypedArrays and Buffers.Class: BroadcastChannel extends EventTarget. ![]()
